It’s been widely reported that almost 40 percent of Americans could be B12-deficient, according to the Framingham Offspring Study.
But if you look more closely at those numbers, you’ll see that this study actually found that 39 percent of people had B12 levels in the “low normal” range—well above the accepted level of deficiency.
In fact, the National Institutes of Health suggests only one to one and a half percent of people suffer from a shortage.
Most of us take in enough from food—milk, eggs, fish, poultry, and fortified cereals (all of which are prominent in the American diet).
That’s not to say everyone is safe from lagging levels.
Some—vegetarians, vegans, people with Chron’s or Celiac disease, and those who abuse alcohol—are susceptible to low levels because of diet choices or absorption issues.
But don’t succumb to a marketed solution off of a self-diagnosis—see your specialist!
Signs of low B12 levels (fatigue, weakness, sore tongue, tingling and numbness in your fingers and toes, difficulty walking, mood change, or memory loss) are also symptoms of other medical conditions.
Fallen for the craze (and worried your levels are in the clear)?
B12 doesn’t build up toxicity like some other vitamins can when taken in excess.
That means that you likely won’t see any negative side effects from too much. Like cellulite cream, it won’t help, but it probably won’t hurt.
